Final answer:
No sets provided in the question contain only words with consonant digraphs without any words with blends. All options either have a mix of digraphs and blends or only blends.
option 'a' is the correct
Step-by-step explanation:
The question asks us to identify which set(s) of words contain only words with consonant digraphs, and no words with blends. Consonant digraphs are pairs of consonants that make a single sound, such as sh in shoe or ch in cheese. Blends are combinations of two or more consonants where each consonant's sound can be heard, such as br in brick or st in stop.
In the given options:
- Set A (Chat, Shell, Bring) includes the word 'Bring' which has a blend br, so it's not just digraphs.
- Set B (Phone, Grape, Plum) includes the word 'Phone' which starts with a digraph ph, but 'Grape' and 'Plum' both have blends gr and pl, respectively.
- Set C (Ship, Chop, Crunch) has all words with digraphs sh, ch, and cr. However, cr in 'Crunch' is actually a blend, so it does not qualify.
- Set D (Sweet, Blend, Frog) contains the word 'Blend' which clearly has a blend bl, so it also does not qualify.
Therefore, no sets provided contain only words with consonant digraphs and no blends.
